IMPROVEMENT IN WASH-BOILERS.

Specification forming part of Letters Patent No. 201,190, dated March12, 1878; application filed November 10, 1877.

To all whom it may concern:

Be it known that I, WILLIAM ANDERSON MILLER, of Rigdon, in the county ofMadison and State of Indiana, have invented a new and useful Improvementin Steam-Washers, of which the following is a specification:

Figure. 1 is a vertical longitudinal section of my improvedsteam-washer, taken through the line 00 m, Fig. 2. Fig. 2 is a verticalcrosssection of the same, taken through the line y 3 Fig. 1.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved steam-washerwhich shall be simple in construction and convenient and economical inuse, saving time, labor, and fuel, efiective in operation, cleaning theclothes quickly and thoroughly, and which will prevent the water fromboiling over upon the stove.

The invention will first be described in connection with the drawing,and then pointed out in the claim.

A represents the boiler, which is made in the usual way, and may be ofany desired size and shape. B is a false bottom, fitting into the boilerA, made slightly conical or highest in the center, and with a hole inits center, in which is secured the lower end of a short tube, 0.

The tube 0 is made with a flaring or funnel-shaped upper end, and in itis placed a tube, D, the lower end of which is slitted or notched toform springs to bear against the inner surface of the tube 0, and thushold the tube D in any position into which it may be adjusted.

The upper end of the tube D is closed, and has a handle, E, attached toit for convenience in adjusting it.

In the tube D, near its closed upper end, is formed a circle of holes,through which the water and steam are projected upon the clothes in theboiler A. The water passes through the clothes and down around the edgesof the false bottom B into the space beneath said false bottom, to beagain forced up through the tubes 0 D, and so on in a continuouscirculation so long as the heat is kept up.

To the sides or ends of the false bottom B are attached springs F, torest against the sides of the boiler A, to keep the said false bottom inplace and prevent it from being raised by drawing up the tube D in thetube 0.

G is the cover, which fits snugly into the boiler A, so that it may beadjusted higher or lower, according to the amount of clothes and waterin the said boiler A. To the sides of the cover G are attacheddownwardly-projecting springs or arms H, which rest against the sides ofthe boiler A and keep the said cover in a horizontal position.

In keepers attached to the upper side of the end parts of the cover Gare placed sliding bolts I, which are held out by springs, so that theirouter ends may enter recesses formed in the ends of the boiler A, tohold the cover G in any position into which it may be adjusted.

The cover G is made slightly conical, and in its middle part is formed alarge hole, in which is secured a dome, J, which is provided with acover, K, and which is designed to serve as a condenser for the, steam,and as a chamber for the boiling water to rise into to prevent it fromboiling over upon the stove.

Having thus described my invention, I claim as new and desire to secureby Letters Patent The combination of the cover G, provided with thesprings or arms H, the spring-bolts I, and the dome J K, with the boilerA, provided with the recesses a, substantially as herein shown anddescribed.

WILLIAM ANDERSON MILLER.
